WINDIVIILL.

To all whom it may concern:

Be it known that I, JAMES S. DoAK, a citizen of the United States, residing at eming, in the county of una, State of 5 New Mexico, have invented certain new and useful Improvements in Windmills; and 1' do hereby declare the following to be a full, clear, and exact description of the invention,

same.

This invention relates to Windmills and particularly side draft eliminated, 7 being thereby prolonged and its efliciency enhanced.

particularly pointed out in the appended claims.

11 describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which- Figure l is a plan view of a windmill constructed in accordance with the invention, thetower being omitted;

a rear view of the windmill, the top of the tower being shown;

*ig. 3 is a side view of what is shown in F ig. 2.

and

12. The windmillrod is indicated at 13 and same is mounted to reciprocate in the tower A in the. usual manposed roller bearings Specification of Letters Patent. Application filed May 23, 1916.

and 17 adjacent the end member 19 is a shaft 21 ,while another shaft 22 is correspondingly mounted in bearings 23 adjacent the end member 18. Fixed on the shafts 21 and 22 respectively are wind-wheels 24 and 25 each including vanes 26. The vanes on the wheel 24 are arranged oppositely to the vanes on the wheels 25 so that said wheels will be rotated in opposite directions. Rotatably in suitable hearings on the frame and 2S and fixed on these shafts are segmental gears 29 and 30 respectively which cofiiperate with the racks 14 and 15. Fixed on the rear ends of the shafts 27 and 28 are arms 31 and 32 respectively the purpose of which will presently appear. Fixed on the shaft 21 are gears 33 which mesh respectively with gears 34 fixed on a shaft 35 journaled rings on the mem- Also fixed on the shaft 35 ad acent the outer face of the member 17 is a disk 36 to which is attached eccentrically one end of a pitman 37, the other end of said pitman being pivoted to the arm 3].. Likewise there is fixed on the shaft 22 gears 38 which mesh. respectively with gears 39 fixed on a shaft 40 journaled in suitable bearings on the members 16 and 17. Also fixed on the shaft 40 is a disk 41 and connected to this disk eccentrically of the latter is one end of a pitinan 42, the other end of said pitman being pivotally connected to the arm 32. By this construction it will be obvious that as the wheels 24 and 25 are rotated y the wind the shafts 27 and 28 will be oscillated as will likewise the gears 29 and 30. This oscillation of said gears operating through the racks 14 and 15 will effect the desired reciprocation of the rod 13 without any side draft being present. Pivoted to the frame C is a rudder 43 which is normally held in active 44. A cable 45 is connected to the rudder 43 at one end and then trained A so that by pulling the cable therudder moved to inactive the influence of the spring 44.

What is claimed is 11 a windmill structure, the combination of a tower, a frame rotatablv mounted on said tower, a windmill rod mounted for reciprocation in the tower, oppositely disposed racks on said rod at the upper end of the latter, shafts rotatably'mounted on the frame on either side of the rod, gears fixed side of the rod 13 are shafts 27 on said shafts respectively and meshing with respective racks, a pair of wind-wheels mounted on the frame, and connections between said wheels and respective shafts 5 whereby the rotation of the wheels in opposite directions will oscillate said gears to reciprocate the rod.

2. In a windmill structure, the combination of a tower, a frame rotatably mounted on said tower, a windmill rod mounted for reciprocation in the tower, oppositely disposed racks on said rod at the upper end of the latter, shafts rotatably mounted on the frame on either side of the rod, gears fixed 15 on said shafts respectively and meshing with Copies of this patent may be obtained for five cents each, by addressing the respective racks, arms fixed on said shafts respectively, a pair of disks rotatahly mounted on said frame on either side of the rod, pitmen connected to said disks eccentrically of the latter respectively and to respective 20 arms, a pair 0 wind-wheels mounted on said frame, and connections between said wind-wheels and respective disks.

In testimony whereof, I affix my signature, in the presence of two witnesses.
